"We love the Mac, and macOS is explicitly created for the unique characteristics of Mac hardware", said Craig Federighi, senior vice president of software engineering for Apple. It'll raise alerts to let customers decide on a case-by-case basis whether they want to let "clever and relentless" data companies track them. All four of the betas are available for free to registered developers, along with Xcode 10, Apple's latest software development framework. Apple is adding a new for your tab, similar to Microsoft' carousel in the Photos app on Windows 10. The challenge is that many users find these pop-up alerts to be a nuisance and just blindly click on them.

At its annual developers conference in San Jose, Apple said that iOS 12 could carry out simple tasks, such as opening apps, up to twice as fast as its predecessor, iOS 11.

If you own a Mac there's could be some new features coming to your desktop with macOS nearly certain to get a refresh.

Fortunately for software developers and tinkerers, that probably means more time will be spent later today talking iOS, macOS, watchOS and tvOS updates, not to mention various ARKit improvements and, most likely, new Siri skills to fend off Alexa and the Google Assistant's rising threats. Also cool: Live Animoji and Memoji are now supported in FaceTime.

And of course, the biggest new feature set to debut in iOS 12 is Memoji, allowing you to create lifelike Animoji.

Wallet on iPhone and Apple Watch adds support for student ID cards, making it more convenient to access everything on campus.

By tapping and "drawing" a line with the app and your device's camera, it provides measurements of 3D objects like a suitcase - in inches and centimetres.

Apple's event is traditionally used to give an early look at the next version of all Apple's software platforms before they are released to the public in the autumn.
